Specircation forming part of Letters `1j". atent No.f 203,418, dated May '7, 1878 application filed l y December 2o, 1877.

eration in connection with a pendulum-lever pivoted to the bracketsupporting the end of the roller, which lever is adapted to be swung bythe raising-cord to cause its upper end to engage or discngage one ofthe studs on the aforesaid head-disk of the drum.

The object of the present invention is to .provide a reversiblearrangement by which the operating devices can be placed at either endof the curtain-roller; and to this end my invention consists in abracket constructed with a journal-bearing for the curtain-roller, aslotted base-plate, and openings at the upper and lower parts of saidbracket, near the baseplate thereof, in combination with apendulum-lever having a lip at its upper end and a stop projecting fromits side, for engaging with a series of studs projecting from a diskattached to the curtain-roller, as will be fully hereinafter described.

In the drawings, Figure l is a front view of my improved curtain-fixtureattached to a Window-casing. Fig. 2 is an end elevation, showing thebracket, pendulum-pawl, and studded disk; Fig. 3, a view of the roller,drum, and studded disk separated; Fig. 4, a view of the inner sides ofthe bracket and pendulum-pawl Fig. 5, a perspective view of a reversiblebracket.

The roller A has formed thereon a tenon, a, having acentral socket, al;and B is a drum, which ts upon the tenon a, and has a flange, b,

which abuts against the shoulder a2 of the roller, the drum extendingbeyond the end of the tenon, and having in its outer edge two notchesmJu, ashort distance apart. Gis adisk of the same diameter as the flangeb, and havingl projecting centrally from one of its sides a spindle, o,and from its other side a hub, c1,

upon. which is turneda journal, c2. N eartheV 'peripheryfand on the sameside of this disk with the hub, and projecting in thesame direc-1 in theopposite direction from its other end,

while in the same direction with the bent arm projects .a stop, F. Grindicates a bracket with a slotted base-plate, g, by which it isattached to the window-frame. In the outer end of this bracket is abearing, g1, for the journal c2 of disk C, and near the base of saidbracket, in obliquely-opposite directions from the bearing gl, are holesg2 g3, into the upper of which, as shown in the drawing, extends thelipped stud e3 of the pawl-lever, the lip e3 preventing the pawl-leverfrom falling therefrom.

lIn placing the parts together, as is usual, the drumB is placed uponthe tenon a, upon which it should fit snugly, being prevented fromturning by two points, p, which are driven into the shoulder of theroller.V The spindle c is then driven into the central socket of thetenon, which extends into the body of the roller, and the disk isbrought snugly against the edge of the drum. Thelipped stud e3 of thependulum pawl-lever is then inserted into the upper hole g2 of thebracket, and when the pawl-lever hangs freely and the journal c2 isinserted in the bearing g1 of the bracket, the stop F is directly in thepath of the studs projecting from disk C, and will prevent the rotationof the disk C by the action of the weight of the curtain W. A knot ismade in one end of the cord 7c, and, the other end of said cord beingpassed through the notches in the hub, the knot is drawn close up to thehub, as shown in the drawing, and the free end of the cord hangsdownward through the slot in arm e.

The fixtures at the opposite end of the roller from those just describedconsist of a simple roller-cap,I,'having a central journal, t', whichextends in the lower part of a reversible bearing, h, in a reversiblebracket, G. The bracketat the other end' is also reversible-that is,both brackets may be changed to opposite sides of the windowl the stud eis inserted in hole g3 of bracket G.

The operation of the invention is as follows While .the curtain is upthe cord is unwound from the drum, and hangs freely downward through theslot of arm e, the pawl-lever hanging directly downward. The stop F pre-Vents the rotation of the disk, and therefore the curtain cannotdescend. Now, when it is desired to lower the curtain, the lower end ofthe oord is drawn downward, throwing` outward the arm e and bringing thestop F toward the hub c1 and out ofthe path of the studs D, thuspermitting the rotation of the disk and the descent of the curtain. Onreleasing the end the lever-pawl will fall back to its natural position,and the curtain may be stopped at any point desired, and when it hasbeen lowered its full length the cord is so wound upon the drum thatwhen pulled downward the roller will be caused to rotate and wind itagain entirely, or much as desired. WhatI claim, and desire secure byLetters Patent, is-

The bracket G, constructed with bearing gl, a slotted base-plate, g, andopenings (1293 at the upper and lower parts of said bracket, near thebase thereof, in combination with the pendulum-lever E, having a lip,e3, at its upper end and a stop, F, and the disk C, havinglaterally-projecting studs D, substantially as and for the purposedescribed.

In testimony that I claim the foregoing I have hereunto set my hand inthe presence of the subscribing witnesses.
